Jessica Biel looks great in the dark. Dark hair, that is.

The 28-year-old 'A-Team' star debuted a rich, chocolate colored hairdo at the Glamour Reel Moments event in Los Angeles, California yesterday, and we must say, it looks fabulous on her. Then again, this Hollywood beauty could walk out the door with bedhead and still look smashing -- oh wait, she's already done that!

From platinum blonde to golden brown to redhead to brunette, Jessica Biel is always on the move with her hair.

In her early years on '7th Heaven,' the actress wore light blonde waves. And when "The Rules of Attraction" premiered, she switched things up with a glossy auburn hue. For her role in "Powder Blue," Biel darkened her strands to a rich brunette, and then shortly after went extreme with a bright blonde.

Biel is perhaps best known for her honey hue with caramel highlights, often worn long in sexy, beachy waves.
